T-Mac is an interesting pick. I think I had him mentally ranked #2 on my list in terms of raw talent and performance, behind D12.
But, if your goal in this thing is to "win", from past experience I think voters care a lot about chemistry and intangibles. Since everybody is ultra-talented, those two things are probably only behind "fit" in terms of how people seem to perceive teams. It's not simply talent accumulation.
And that's the rub with McGrady. There's a perception, at least among some, that's he was selfish, lazy, and/or unfocused on winning. I don't think his recent video talking about how he didn't want to play for Pitino in college or the pros because he demanded too much helps his cause much. There's no reflection from him that he was an immature player making a bad choice by tanking his interview. He still feels justified.
Controversial take: McGrady had more pure talent than Kobe. But, he didn't have Kobe's drive.
